Drivekey Update and the Homebrew Channel Quesitons

Sorry for double posting , I just noticed the drivekey subforum is dead.

So i have a wii with a drivekey installed. I'd like to install homebrew channel and would like to know if the standard method will work or if there's any special instructions required. Also, the sw version is 1.0 and the fpga version is 2.0 . I see on the now obsolete drivekey website that there's a new version available. Is there any point in updating and are there any downsides to keeping it unupdated?
